This game recently came out for PS3. I´m playing it and despite that the plot is a bit tame it´s a really cute game. I just made it out of Fort Fermata into Hanon Hills on my quest to find the evil Count Forte
There´s alot of music references (Chopin first special attack is called "Piú Grave"

) which is fun, but also some straight "facts" for pedagogical purposes about Chopin's life and his most famous compositions which each chapter in the game evolves around. First chapter is called "Raindrop" and the 2nd "Revolution"
During the game you also acquire score pieces which you get to play with others and if you play well you´ll be granted a reward.
Unless you think Chopin and his art is too holy to be made into something trivial as a computer game I guess you don´t want to play this, and I don´t think any Europeans would ever come up with the idea of making a game of Chopin on his deathbed. Nonetheless, I find it very charming and a great way to get the music across to young people and those that are not as informed about Chopin's music as most users on this forum.
